Surecast isn't the greatest, but if you're getting hammered and need a heal it works. Swiftcast is mostly amazing because of using it to raise someone that died. Virus and Eye for an Eye are proxy defensive CDs for the tank. I don't have Eye for an Eye yet as Arcanist is only 30, but I generally pop Virus when I know I have to do a lot of movement soon.

Thunder is basically worthless all around because it uses too much MP and at 50 in groups I pretty much never nuke anything. Ruin sucks as a cross class ability. Cure > Physick. Is there anything I'm missing here? I don't think there's a fifth cross-class ability worth picking up.---"For what is a man profited, if he shall gain the whole world, and lose his own soul? ..."- Matthew 16:26

Swiftcast more or less includes Surecast in it -- A spell used under its influence will come out every time, even if you're moving. Great crossclass ability for anyone that can use it.---The Answer May Be 42, But 42 Is Not The Answer. ~~~"Nature compensates for weakness. This is why stupid people usually have big mouths." - IPF

unfortunately, there isnt much choice for any job's cross class skills. you're basically stuck with the best 4-5. it would've been nice if they let loose a little and gave us a little more choice, bio/miasma/aetherflow would've been great as a cc skill---PSVita no games? http://www.gamefaqs.com/boards/620272-playstation-vita/66080697http://www.atlus.com/res/p4g_faithful_reviews_1.jpg
